Biodiesel Machine The near future, haze of another round of heavy mist is sweeping across much ground of our country north. Of mist haze will raid, threw into confusion again industrial production and the order that common people lives, the worry of harm all without exception with healthy to human body to mist haze people is heavy. And the topic that how governs haze to also become all circles heat to discuss again. A few days ago, reporter of newspaper of Chinese chemical industry is interviewed can understand when expert of industry of second birth energy, originate as a result of biology derv raw material deserted grease, and have low sulfur, decrease the characteristic such as the platoon, with the biology diesel oil that its receive after concoctive petrifaction derv concoctive fuel can aid a car to decrease a platoon, quite significant to reducing mist haze.
Car tail gas is one of mist haze prime criminal
The formation of mist haze basically comes from discharge at car tail gas, industry, building raise dirt, rubbish burns wait for a variety of fountainhead, it is a variety of pollution normally the source mixes action and cause mist haze weather. And be in different area, the origin of mist haze has each different.
Country but director of alliance of strategy of innovation of technology of industry of second birth energy, China but Zhang Ping of chairman of guild of second birth the sources of energy expresses, car pollution discharges one of main source that are the PM2.5 in air, 30 £¥ of £¥ ¡« . And analytic to the origin of Beijing PM2.5, the “ contribution ” of the car thinks to be in commonly 10% ¡« 50% , majority thinks to be in 20% ¡« 30% .
Zhang Ping complement says, the car discharges azotic oxide and VOCs (volatile organic compound) the proportion that holds azotic oxide and VOCs to discharge gross respectively is as high as 42% with 32% . Azotic oxide and VOCs can produce actinic reaction to produce O3 in atmosphere not only, and can produce nitric acid salt and collosol of 2 organic gas 2 times, accentuate thereby mist haze degree, make its endanger farther aggravate.
Biology derv aids a car to fall row
Zhang Ping expresses, the sulfur content in biology derv is low, the discharge capacity of the 2 oxidation sulfur that also makes its combustion is generated and sulfide is small. Secondly oxidation sulfur and sulfide discharge capacity compare petrifaction derv to be able to decrease about 30% (when having activator, can decrease 70% ) ; The scent that pair of environments do not contain to cause pollution in biology derv hydrocarbon of a group of things with common features alkyl, the waste gas harm to human body under petrifaction derv. In the meantime, biology derv contains oxygen the volume is high, of the carbon monoxide when its burn discharge make an appointment with than decreasing with petrifaction derv photograph 10% (when having activator, can decrease 95% ) ; The biology degradation sex of biology derv is tall, biology derv car discharges waste gas to reduce 20% ¡« 75% . #p#·ÖÒ³±êÌâ#e#
As a result of a variety of advantages of biology derv, the use of concoctive fuel meets biology derv improve the environmental protection performance of diesel engine effectively. In Shanghai implement limited company of environmental protection science and technology participated in Shanghai 104 buses use biology derv travel the practice of one hundred and thirty-five thousand eight hundred kilometre. Yang Jianbin of this company inspector general expresses, effective way discharges an experiment in, use mix into of fair car of ¢õ of ¢ô of ¢ó , country, country mixes the country the concoctive fuel of 10% biology derv will reduce carbon monoxide to discharge 5% , reduce grain contaminant to discharge 10% , at the same time the crucial component surface such as engine piston, valve, fuel injector accumulates carbon without generation.
Zhang Ping introduces, biology derv with its advantageous but 3 large dominant positions already endured second birth, cleanness and safety of world each country take seriously. Use biology derv is concoctive fuel, already was decreased to discharge a method as the mainstream by the developed country, and derv of a lot of national regulation petrifaction do not add biology derv to cannot enter the market. The scale of derv of the biology in concoctive to biology derv fuel, a lot of countries made a provision: 27 countries are the European Union 5% ¡« 7% , the United States is 5% ¡« 20% , canada is 2% ¡« 5% , thailand is 5% , argentina is 7% , south Africa is 2% etc.
Zhang Ping expresses, using deserted edible grease to produce biology diesel oil is efficiency of technical maturity, changeover the natural resources with additional high cost turns tall, product method. Amount of generation of grease of our country deserted edible is huge, the 20% ¡« that take edible oily consumption according to reckonning deserted grease produces an amount 30% . With our country edible oily consumption was calculated 28.75 million tons 2014, can produce 5.75 million ¡« every year 8.62 million tons of deserted grease. The changeover rate that uses the deserted grease such as ground channel oil to produce biology diesel oil as raw material can amount to 75% ¡« 80% , annual producible derv of about 7 million tons of biology.
Zhang Ping points out, because detect,analytic technology lags behind, execute the law supervisory difficulty, a large number of deserted edible grease pass table of circumfluence of subterranean industry catenary to had made one of dense disease that affect safety of our country food. To this, the government should rely on compose of biology derv industry to build resource of oily ” of “ ground channel to change use advocate channel, can solve problem of table of circumfluence of oily ” of “ ground channel thoroughly already, can aid force to fall again haze, kill two birds with one stone of it may be said.
